る光スイツチ。 A first optical path for guiding the optical signal emitted from the first optical transmission path to the optical receiver, and a second optical path for guiding the optical signal output from the optical transmitter to the second optical transmission path. Separately, a first plate having a semi-transparent membrane applied to the contact surface is provided.
a right-angle prism having a reflecting surface and a second reflecting surface, and when bypassing the optical signal from the first optical path to the second optical path, the position of the right-angle prism is controlled via a driving means. , inserting the first reflective surface side of the right angle prism into the first optical path,
The emitted light from the first optical transmission path reflected by the first reflective surface is reflected by the second reflective surface and is incident on the second optical transmission path, and is also incident on the right angle prism. An optical switch characterized in that a part of light is guided to the optical receiver through the semi-transparent film.
